. aspire-nan med J3me iv, an. eridluox'a dfia To all whom it may concern:

. Be it known that 1, CHARLES L. l-lnno, a citizen of the United States, and resident of Rochester, in the county of Monroe and State of New .York, have invented certain new and useful Improvements in Mixers, of which the following is a specification. v

The present invention relates to internal combustion engines and more particularly to the means for supplying fuel to such engines, an object of this invention being to provide means which will act on the'fuel as the latter is discharged by the manifold into the valve chamber to effect an eliicient mixture of the fuel. Another object of the invention is to produce a whirling action of the fuel as the latter enters the valve chamher, so that the unmixed liquid fuel will be distributed over a wide area on one of the walls of the valve chamber and in thi sway will 'bemore readily and eii'ectively vaporized.

To these and other ends the invention'consists of certain parts and combinations of parts all of which will be hereinafter described, the novel features being pointed out in the appended claims.

in the drawings I Figure 1 is a view of the manifold of a gas engine used in the Ford automobile, the mixing devicebeiug shown in position in the two outlets of the manifold; Fig. 2 is a fragmentary view of a Ford engine casing and a portion of the manifold showing the mixing device partially in section; and

Fig. 3 is a fragmentary sectional view of the manifold and the engine casing showing the mixer in side elevation. i

In the Ford engine the fuel passes from the carburetor (not. shown) into a manifold 1 which conducts it by two branches to two valve chambers 12 formed in a" casing in. which the cylinders are also formed. Each izcd fuel collects on the wall to be vaporized by the heat of said-wall or by the fuel passing over said wall. In many instances the fuel is too rich with unvaporizcd fuel and as a consequence the latter accumulates to such an extent that it is drawn unvaporized within the cylinders.

According to this invention, the fuel, as it 1 enters the valve chamber 2, is given a whirling action which spreads the fuel over a greater area of the wall 4 than is possible without this whirlingaction', and as a consequence the unvaporized fuel does not accumulate at one point, so that" it is possible to vlaporize the fuel more easily. and effective y.

This mixing device, in this instance, utilizes as its-support the usua-l'ring 6 which fits within the manifold and the opening of the valve chamber, and itcomprises a lurality of blades 7 having a slight spire or travels at the center ofthe 'fuel column while the vaporized fuel is outermost. The mixer by being formed as described has the most .cfi'e'ctive portions at the center,-so that the' unvaporized fuel is influenced most strongly by the blades and is whirled over the face of the Wall 4, while the vaporized fuel has a substantially free path owing to the spaces 8.

between the blades. i

What I claim as my invention and desire to secure by Letters {Patent is:

1. In combination with a: manifold of a gas engine, a mixer arranged in the manifold and having stationary blades extending outwardly from a line ax1ally of the flow of material through the manifold, said blades gradually decreasing in width from the axial line to their outer edges and being twisted spirally, the outer edges of the blades being separated so that fuel piissing the-mixer adjacent the outer edges'does not impinge the blades and does not have the direction of its travel changed, and the twisted portions of the blades acting to throw outwardly a portion of the fuel column into the non-deflected portion, thus producing a mixture of the column 'without any material retardation of such column. I r

2. In cmnbination with a manifold of agas engine, a mixer having stationary blades so formed as to permit the free passage with- 75 their outer'edges toward the axial line. 1; is well recognized that the unvaporized fuel out deflection of the- Ollttl' prntion-of the column of fuel PlSr5i1lg through the inanifold, and to \\i'llli an inner portion oft-he column outwardly info the outer portion of ,3 the column.

3. A mixing device comprising a ring and a plurality of screw hhules rigid with and plOJGQ-t-ll'lg from -the ring secured to each CHARLES LABEED.
